Tannic acid Description
What is Tannic acid?
Tannic acid can be used for tanning leather, ink manufacturing, gluing paper and silk, boiler descaling, etc. It can also be used as a mordant, a clarifying agent for beer and wine, a gelling agent for rubber, etc. Tannic acid is used as a fixing agent, mordant, and synthetic dye in textile printing and dyeing.
Tannic acid is used for precipitation and weight determination of beryllium, aluminum, gallium, indium, niobium, tantalum, and zirconium; Used for colorimetric determination of copper, iron, vanadium, cerium, and cobalt; Used as a precipitant for proteins and alkaloids; Used as an external indicator for ammonium molybdate titration of lead.
Tannic acid can inhibit bacterial growth and absorption of intestinal endotoxins, and can be used to prevent and treat diarrhea. Medicinal tannic acid can be directly used in beverages, frozen products, candies, ice cream, and meat products; Used as a burn and scald wound astringent, gastrointestinal hemostatic agent to prevent infection; It can be made into tannic acid glycerol, tannic acid protein, tannic acid ointment, anti cold agent (N-bis (amidine) morpholine tannate), health promoter, insect repellent, insecticide, anti radiation agent, contraceptive agent, and special toothpaste.

Tannic acid Applications
- Food grade tannic acid is mainly used as a clarifying agent for beer, wine, and low alcohol beverages, and can also be used in pineapple protease food processing and other fields. Tannic acid can be used as a food additive. Usually mixed with vitamin E, vitamin C, or gallic acid before use.
- Tannic acid can be used as a mordant in dyeing, as well as in the production of gallic acid, pyrogallic acid, leather tanning agents, rubber coagulants, protein and alkaloid precipitants, and reagents for the determination of metals such as beryllium, aluminum, nickel, and copper.
- Tannic acid is mainly used in industries such as medicine, ink, printing and dyeing, leather and metallurgy, as well as water treatment. Tannin has flocculation, deoxygenation, scale inhibition and sterilization effects in the water treatment process.
